This article describes the technical side of buying in HeatAlgo: what happens after you click "Continue to payment", who the seller is, where to find the invoice and how to manage the subscription. If you are looking for what is free and what a report unlocks, start with the free plan and reports.
How a purchase works
You start a purchase in two places: on the "Billing" page (account menu, "Plan and billing") with "Buy credits" or "Get a subscription", or in a project with "Unlock the full report" when you have no credits. The "Unlock" dialog opens with two plans:
- "Report" - for one house and one job; you choose the number of reports, and the unit price drops at 3, 5 and 10,
- "Subscription" - for everyday work; you choose the term: 1, 6 or 12 months.
In the same dialog you choose the currency (PLN or EUR) and see the net total. "Continue to payment" takes you to the Stripe payment page. There you enter card details or pick Apple Pay, Google Pay or Link, and if you are buying for a company, you enter the tax ID. After paying you return to the app on the "Confirming your payment" screen; confirmation usually takes a few seconds, then you see "Payment confirmed" and access is active.
Credits appear on the account immediately and stay indefinitely. The subscription activates immediately for the chosen term.
Who the seller is and where the invoice comes from
A purchase in the app is settled by Stripe, and Stripe is the seller. It applies tax by the buyer's country and issues an invoice with the HeatAlgo name and the product details. You receive the invoice in a separate email from Stripe after every payment - including every subscription renewal.
All invoices and the saved card are under "Invoices and card at Stripe" on the "Billing" page. A Stripe page opens and you return to the app from it. Purchase history is also in the "Orders" section of the app: every payment has a date, an amount, a status ("Paid" or "Refunded"), the seller and the invoice number.
Buying for a company? You enter the tax ID in the Stripe payment form, before paying - the app reminds you in the purchase dialog. The tax ID from the form goes on the invoice.
When paying in złoty the app shows the gross amount at the Polish 23% VAT rate as information; the final tax is applied by Stripe on the payment page by your country, and you see it before paying. Purchases are not possible from countries restricted by the payment operator - the list is on the pricing page.
Payment methods
On the payment page you pay by card, or with Apple Pay, Google Pay and Link. BLIK and Przelewy24 are not available in this settlement. Payment by bank transfer against an invoice is arranged only for companies doing many houses a month, as part of an individual quote - there HeatAlgo is the seller and issues a VAT invoice at 23%. Such orders appear under "Orders awaiting an invoice" with the status "Invoice on the way", "Invoice issued", "Paid" or "Cancelled".
Subscription: term, renewal, cancellation
The Installer subscription covers every project on the account, with no revision window. You buy it for 1, 6 or 12 months (500 zł, 2,400 zł, 4,200 zł net; in euro 120 €, 575 €, 999 €). A longer term means a lower price per month. Under "Your plan" you see the status "Active" and the "Paid until" date.
The subscription renews automatically at the end of the paid period from the saved card. On the six-month and annual terms you receive a reminder email with the amount two weeks before the renewal; the monthly plan renews each month without a separate reminder. If the renewal payment fails, Stripe retries, and access continues in the meantime - in that case update the card with "Manage card".
Cancelling: under "Your plan" click "Cancel subscription". The dialog shows three things: until when you keep access, how many projects lose report export after that date, and that projects and calculations stay on the account. After confirming, the status changes to "Ending" and access lasts until the paid date. Until then you can change your mind with "Resume subscription" - we delete nothing, and resuming restores export in every project.
After the subscription ends, projects unlocked under it return to preview as far as export goes: PDFs downloaded earlier stay yours, and a new version can be downloaded after buying a report or resuming the subscription. While one subscription is active you cannot buy a second one - the app refuses with "You already have an active subscription".
Card and payment details
You change the card with "Manage card" on the "Billing" page - it opens a Stripe page where you enter the new card, and you return to the app. If the app answers "There is no card saved for this account, so there is nothing to manage", no card payment has been saved yet - the card appears with the first purchase.
HeatAlgo does not store card details; everything about the card and invoices happens at Stripe.
When something went wrong
- "This is taking longer than usual" on the confirmation screen - the payment may still have succeeded; check the "Billing" page shortly.
- "Payment not found" - check "Billing"; if you were charged, write to us from the confirmation screen, and the payment reference is attached automatically.
- "The payment could not be opened. Try again in a moment - nothing was charged" - a momentary problem on the payment side; repeat the purchase.
- A refunded payment - it has the status "Refunded" in the payment list, and the unused credits from that payment disappear from the account.
- Questions about an invoice correction - write to us from the account menu ("Email us").
Refunds and withdrawal
Cancelling a subscription takes effect at the end of the paid period: you keep full access until then, and the fee for unused time is not refunded pro rata. Unused report credits do not expire, so they stay on the account for the next job.
As a consumer you have 14 days to withdraw from a distance contract. A report and a subscription are digital content: at purchase you confirm that you want the project unlocked or the subscription activated immediately, and you acknowledge that once that is fully delivered the right of withdrawal lapses. If you withdraw effectively before full delivery, the payment comes back to you within 14 days by the same method you paid with. You can always withdraw from subscription periods that have not started yet - that is the ordinary cancellation described above.
For card purchases in the app the seller is Stripe, and you exercise the right of withdrawal against Stripe under its terms; against us, on the company route. The full rules are in the Terms of Service (§8 and §9). A refunded payment shows as "Refunded" in the payment list, and the unused credits from that payment disappear from the account.
